As Warp said, this just won't be done. It has been considered, and 
decided to be a bad idea. Convert to JPEG in an external program, where 
you can adjust the settings to get the best results.

There are many problems with this idea. First, the whole image needs to 
be re-rendered. Changes to an object can affect any portion of the 
image, so updating the image just won't work right.

Selecting an object to render could be useful during the development 
process, but would require that the entire scene be held in memory, and 
other big changes. Just use the existing partial rendering feature.
